You can configure a step to apply a regular expression to the values in an input string. The operation compares the values in an input string to the values in a regular expression. The step writes the label that you specify for the value in the output.
On the
Configuration
tab, select the option to add a step to the asset.
The
Add Step
dialog box opens onscreen.
Select
Regular Expression
as the step type.
Select the Built-in or Custom option.
To select a regular expression from a list of built-in expressions, select Built-in.
To enter a regular expression that the step will use, select Custom.
Select or enter a regular expression that describes the character composition of the values that you want the step to find at run time.
If you select Custom mode, enter a label that describes the data that the regular expression finds in the input string. If you select Built-in mode, the regular expression adds a default label.
You can accept the default label in Built-in mode or enter a label that you prefer. To change the label, select the User-Defined option.
